It took extra time and 12 goals to decide the two-leg Eastern Conference final. Toronto will host the Seattle Sounders on Dec. 10 in the MLS championship game, becoming the first Canadian team to play for the title.

Toronto trailed 3-2 after Game 1 in Montreal and fell further behind after the Impact scored first.

Only once before in MLS playoff history had a club trailed by as many as three goals in a two-leg aggregate series and come back to wine. The San Jose Earthquakes were down 4-0 in 2003 before rallying to beat the Los Angeles Galaxy 5-4.
